TANK-HEATER.

Application filed June 23, 1917.

To all whom it may concern: Be it known that we, JOHN H. MALONE and Groin F. MALONE, citizens of the United States, residing at Minden, in the county of Kearney, State of Nebraska, have invented certain new and useful Improvements in Tank-Heaters; and we do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enablepthers skilled in the art to which it appertains to make and use the same.

This invention relates to heaters for stock tanks.

The object of the invention is to provide improvements in heaters for stock tanks, principally by constructing a heater in which oil is employed as a fuel.

It is furthermore an object of the invention to provide a heater in which a circulation of the water in the tank is set up, so that the water will be uniformly heated.

Furthermore, it is intended to provide a tank heater in which a solid fuel grate may be substituted for the oil fuel burner upon occasion, with a minimum of effort and expenditure of time.

IVith the above objects in View, and such others relating to the details of construction as may hereinafter appear, our invention will now be fully set forth and described, reference being had to the accompanying drawings.

In the drawings Figure 1 is a vertical section through a stock tank in which our invention is mounted,

Fig. 2 is a vertical section through the heater,

Fig. 3 is a section on the line 4-4 of Fig. 2,

Fig. 4 is a plan view of a cover plate, and

Fig. 5 is an end view of the device.

Referring more particularly to the drawings, 1 represents a stock tank of a well known form, within which the improved heater is built to fit. The heater body consists of a horizontally disposed drum 2, a receiving chamber 3 which rises from one end of the drum 2 and forms an inclined extension thereof, the chamber 3 being provided with a removable cover 4, having the draft valve 5. Rising vertically from the drum 2, substantially at a central point, is a smoke drum 6 from which a chimney 7 is up- Specification of Letters Patent.

wardly projected, the latter being controlled by means of a damper 8.

The drum 2 is provided with a pair of heating coils 9 which are preferably U- shaped in construction, and extend rearwardly from the end 10 of the drum 2 epposite the extension 3 thereof, to which their open ends are attached and through which they project, so that a circulation is set up through the coils. The coils 9 stand vertically within the drum 2, that is, their arms lie one above the other so that a circulation is generated from the lower arm to the upper arm and through the tank water.

Projected through the cover 4.- ,is a fuel conduit 11 to whose lower end is attached a burner 12, which, when the conduit 11 is projected into the extension chamber 3, stands within the drum 2, between the coils 9, so that its flames will heat the water in the coils. In order to properly distribute the flames of the burner, a spreader plate or baffle 13 is carried by the latter, so as to direct the flames against the coils 9. The burner.12 may be supplied with fuel from any suitable supply, 1n the present instance a pressure tank 14 being shown, the oil flowing from which is controlled by means of the pet cook 15 located in the upper end of the conduit 11.

The burner and the conduit 11 are thus readily removable from the heater. An annular flange 17 is located near the lower end of the chamber 3, and said flange 17 is employed to support a baflle plate 18, which will prevent the improper circulation of the heat in the chamber 3,but which is provided with an aperture 18 for admitting a combustion supply of air to the burner. The baffle plate 18 is removable with the burner, and when so removed, it is obvious that the extension chamber 3 may form an ordinary combustion chamber for burning solid fuel.

In order to hold the heater in the bottom of the tank, we encircle the drum 2 with a pair of straps 19 to which are secured the loops or yokes 20 through which weights may be extended to anchor the heater in the bottom of the tank.

In the use of our improved structure, we find that the water is quickly and uniformly heated, in that the temperature to which it is desired to heat the water can be accurately gaged by means of the pet cook 15.

Furthermore, the device heats a large' body of Water with a comparatively small amount of fuel.

What We claim as our invention is A tank heater comprising a drum adapted to lie horizontally Withln the tank and having one end portion angularly inclined to extend above the Water line of the tank, a smoke box on top of the drum, a removable oil burner extending longitudinally Within the inclined portion of the drum, a support disposed intermediately in said extended portion and a baffle plate removably engage- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.

able on the support to prevent movement of heated air upwardly in the angularly inelined end portion during the use of the oil burner, said support being adapted to support a 'rate for solid fuel upon removal of the bafli e plate.

In testimony whereof, We aflix our signatures in the presence of two Witnesses.
